More Package adding info User Definables Graphics Additional Packages Info and UserDefinables LATEX for Math and Science Adding local tex folder TeXLive and MikTeX have the capability of letting users place packages outside of the installation paths. This is convenient when neither programs install the packages automatically. Also, in Windows you do not need to run a program as administrator, which is the most compelling reason to do this. There is also less digging for the actual folder or file. TeXLive Instructions MikTeX Instructions Note that you only need to run texhash after the first time you add a package, and not each time you edit the package. Also, the folder you point as a root must contain tex\latex, which is where you place packages, you can place them in their own folders or just the latex folder. More Package adding info User Definables Graphics Who cares? What if a math command like sin, \sin is not defined for your operator, e.g. \dom, \ran, or \Res? What if I am too lazy to write out the whole command? What if I don’t like the look of the existing command? More Package adding info User Definables Graphics Who cares?

What if I don’t like the look of the existing command? More Package adding info User Definables Graphics DeclareMathOperator So LATEX doesn’t have \dom or \ran, built-in, so that is what \DeclarMathOperator is for. Simply place \DeclareMathOperator{\dom}{dom} and \DeclareMathOperator{\ran}{ran} in the preamble on their own lines. Now you can use \dom x and \ran x, which look like dom x and ran x respectively. The importance is that \DeclareMathOperator makes the text upright and adds a small space after the command. More Package adding info User Definables Graphics DeclareMathOperator∗ So the default behavior for subscripts and superscripts for \DeclareMathOperator is ranx and domx . What if I want it to be like \sum, i.e. ∞ X ? n Use \DeclareMathOperator*. For example, \DeclareMathOperator*{\Res}{Res}. So it will appear as 1 Res ? z=0 z More Package adding info User Definables Graphics The similarities between newcommand, renewcommand, and providecommand These commands each have the same declarations: \*command{\Name}[NumberOfArguments]{The command} A couple examples \newcommand{\bbR}{\ensuremath{\mathbb{R}}} results in R when you type $\bbR$. \newcommand{\dotssub}[3]{\ensuremath{{#1}_{#2} results in a1 an when you type \dotssub{a}{1}{n}. \newcommand{\Iff}{if\textcompwordmark f\xspace} results in iff when you type \Iff.

More Package adding info User Definables Graphics The differences between newcommand, renewcommand, and providecommand \newcommand will stop if the command has been declared before by another package. \newcommand will return an error if it does find it has already been declared. \renewcommand will overwrite any command declared before, and not warn you that it overwrote it. Be careful with this command. \providecommand is like newcommand, but doesn’t warn you if it has been declared before. This is the safest to use, and should be used most often.
